Hi Bruce I've had good luck touching between coats with a very fine wet/dry sand paper, then wiping down with a tack cloth. Let dry for a few minutes, then apply the next coat. Finish with a couple coats clear coat. For smaller parts and tubes, an hour baking in the oven, at about 175-200, hanging on wires from the top grate works really well. I preheat the oven past 200, turn back down and set the parts in. Switch the "Timed bake" to turn the oven off in an hour. That way it rarely goes back on, and it can be let to cool on its own. Don't forget to turn on the fan to vent the house .The finish is hard, smooth and immediately usable. I have the advantage of kitchen diva, so I clean the oven after use and don't have to ask anyone's permision. Sorry if this sounds like a recipe... I just listed one for porkchops on another forum...
